You could do that on a smartphone. Our daily average for August so far is 26869 hits (which isn't much /at all/) and Tomcat 5.5.x isn't batting an eyelash at that. We run with a measly 10 database connections in our pool, too. Mean response time (on the server, so there's no network time taken into account) for all requests over the last 6 months or so is 135ms (weighted average... unweighted average is 154ms). That's with an old version of Tomcat, run through Apache httpd/mod_jk, using the blocking I/O AJP connector, using a 3GHz quad-core CPU with a heap size of a mere 500MiB (I thought we were using 192MiB, but it looks like I forgot to constrain the heap size the last time I launched the JVM). The JVM has never crashed in the 7 years we've been running this webapp (it's actually 4 webapps, running in 4 separate JVMs), nor has Tomcat. The only unexpected downtime we've ever had was when we busted the heap once long ago (when we were running under a 64MiB heap) and that was because we had a poor capacity plan, not because of Java/Tomcat. > and as much concurrent database connections. 1500 database connections might be a lot to configure. Remember that you'll likely get those 1500+ hits during a 24-hour period (or even an 8-hour period) and not all at once. You probably need far fewer database connections than you think you do. > I know alot depends on the applications architecture but just how > good is tomcat? Really effing good. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkx1LEgACgkQ9CaO5/Lv0PD6rACglH6ICeQl4hpKctAaC9UZiFUN djIAn2DzK0AvMsC+hedrInR8SfCpud6a =XWVz -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
